You discover a new dominant mutation that causes memory loss in middle aged adults. you identify a genetic variant on chromosome 4 that co-segregates with the disease within a family. the pedigree shows each individual's genotype at that marker (the two alleles are 1 and 2) and whether they have the disease (black symbols).part abased on the pattern of inheritance in the pedigree, what is the most likely genotype for individual {\rm i}-1 (assume he is heterozygous for the disease causing mutation). d stands for the disease mutation, and d stands for the recessive allele. a. d 1 / d 2b. d 1 / d 2c. both of the options above are equally likely. part bbased on the phase of alleles on chromosomes in generation {\rm ii}, is there any evidence of recombination among the eight offspring in generation {\rm iii}? choose the correct explanation. a. yes, iii -6 is a recombinant. b. yes, iii -1, iii -2, iii -4, and iii -7, are recombinants. c. yes, iii -3, iii -5, and iii -8 are recombinants. d. no, there is no evidence
